Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: A washing and drying integrated machine, such as Figures 1-4 As shown, the machine includes an integrated main body 1, which comprises a washing machine 2 and a hot air drying chamber 3. A hot air recovery device 4 is installed between the washing machine 2 and the hot air drying chamber 3 to recover and reuse the high-temperature exhaust gas discharged from the hot air drying chamber 3. The hot air recovery device 4 includes a first hot air duct 5, a fan 6, a second hot air duct 7, several heaters 17, and a third hot air duct 9. Several air outlets 14 are respectively opened on the side of the second hot air duct 7 and the third hot air duct 9 that are close to each other. The diameter of the first air outlet 14 is the same as that of the second air outlet 15. The first air outlet 14 is opposite to the second air outlet 15. The heater 17 includes a heat-conducting roller 8, a bearing 10 and a preheating roller 11. The outer diameter of the heat-conducting roller 8 is the same as that of the first air outlet 14 and the second air outlet 15. The two ends of the heat-conducting roller 8 are fixedly connected to the first air outlet 14 and the second air outlet 15 by welding and are interconnected. Welding improves the airtightness, prevents heat loss and ensures better circulation of hot air.

[0021] like Figure 2 and Figure 3 As shown, the heat-conducting roller 8 has a hollow structure along its length, allowing hot air to circulate within it. Two bearings 10 are fixedly connected to the outer wall of the heat-conducting roller 8. The outer diameter of the heat-conducting roller 8 is smaller than the diameter of the inner ring of the bearing 10. The two bearings 10 are located on the side of the heat-conducting roller 8 closest to the second hot air pipe 7 and the third hot air pipe 9, respectively. The two ends of the preheating roller 11 are rotatably connected to the two bearings 10. The fabric is distributed in a wave-like pattern on several preheating rollers 11, which allows the fabric to be stretched and heated more evenly when conveyed on the preheating rollers 11, thus improving the preheating effect of the preheating rollers 11.

[0022] like Figure 3 and Figure 4 The length of the preheating roller 11 is the same as the distance between the two bearings 10. The length of the preheating roller 11 is less than the length of the heat-conducting roller 8. A cavity 12 is formed between the preheating roller 11, the two bearings 10, and the heat-conducting roller 8. Four ventilation grooves 13 are circumferentially arranged on the peripheral wall of the heat-conducting roller 8. All four ventilation grooves 13 are interconnected with the cavity 12. The length of the ventilation grooves 13 is less than the distance between the two bearings 10, which allows the hot air in the heat-conducting roller 8 to have better contact with the preheating roller 11, accelerates the heating of the preheating roller 11, and improves the preheating efficiency. Both the heat-conducting roller 8 and the preheating roller 11 are made of oxygen-free copper. Oxygen-free copper has extremely high thermal conductivity and good corrosion resistance, which improves the heat conduction effect and service life of the heat-conducting roller 8 and the preheating roller 11.

[0023] like Figures 1-4As shown, one end of hot air duct 2 7 is fixedly connected to the air outlet of fan 6 by welding. Hot air duct 2 7 and fan 6 are interconnected. The end of hot air duct 2 7 away from fan 6 is closed, so that all the hot air blown out by fan 6 is discharged into air outlet 14. One end of hot air duct 1 5 is fixedly connected to the top of hot air drying box 3. Hot air duct 1 5 and hot air drying box 3 are interconnected. The end of hot air duct 1 5 away from hot air drying box 3 is fixedly connected to the air inlet of fan 6. Hot air duct 1 5 and fan 6 are interconnected. When fan 6 starts, it removes the high-temperature waste air from the hot air drying box 3. Air is drawn into hot air duct 1 5 and then discharged into the heat-conducting pipe through hot air duct 2 7. Hot air duct 3 9 is fixedly connected to the side of the washing machine 2 near the hot air drying box 3 and away from hot air duct 2 7. The end of hot air duct 3 9 near the hot air drying box 3 is closed, and the end of hot air duct 3 9 away from the hot air drying box 3 is connected to an exhaust gas purification device, so that the discharged high-temperature exhaust gas is purified and filtered. A conveyor roller 16 is installed inside the hot air drying box 3. The conveyor roller 16 and the preheating roller 11 are on the same horizontal plane. The fabric is conveyed into the hot air drying box 3 for drying through the conveyor roller 16 inside the hot air drying box 3.

[0024] Working principle: The motor drives the fan 6 to transport the hot air in the hot air drying box 3 through the hot air pipe 5 and the hot air pipe 7 to several heat-conducting rollers 8. The hot air in the heat-conducting rollers 8 can be transported into the cavity 12 through several ventilation grooves 13. The hot air in the cavity 12 transfers the temperature to the preheating rollers 11 through heat transfer. When the fabric is conveyed on the preheating rollers 11, the temperature on the preheating rollers 11 is transferred to the fabric through heat transfer, so that the fabric is preheated before entering the hot air drying box 3.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
